+                       59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+	    How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program; if not, write to the Free Software
+    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+PHP-gettext 1.0 (https://launchpad.net/php-gettext)
 
+Copyright 2003, 2006, 2009 -- Danilo "angry with PHP[1]" Segan
+Licensed under GPLv2 (or any later version, see COPYING)
+
+[1] PHP is actually cyrillic, and translates roughly to
+    "works-doesn't-work" (UTF-8: Ради-Не-Ради)
+
+
+Introduction
+
+    How many times did you look for a good translation tool, and
+    found out that gettext is best for the job? Many times.
+
+    How many times did you try to use gettext in PHP, but failed
+    miserably, because either your hosting provider didn't support
+    it, or the server didn't have adequate locale? Many times.
+
+    Well, this is a solution to your needs. It allows using gettext
+    tools for managing translations, yet it doesn't require gettext
+    library at all. It parses generated MO files directly, and thus
+    might be a bit slower than the (maybe provided) gettext library.
+
+    PHP-gettext is a simple reader for GNU gettext MO files. Those
+    are binary containers for translations, produced by GNU msgfmt.
+
+Why?
+
+    I got used to having gettext work even without gettext
+    library. It's there in my favourite language Python, so I was
+    surprised that I couldn't find it in PHP. I even Googled for it,
+    but to no avail.
+
+    So, I said, what the heck, I'm going to write it for this
+    disguisting language of PHP, because I'm often constrained to it.
+
+Features
+
+  o Support for simple translations
+    Just define a simple alias for translate() function (suggested
+    use of _() or gettext(); see provided example).
+
+  o Support for ngettext calls (plural forms, see a note under bugs)
+    You may also use plural forms. Translations in MO files need to
+    provide this, and they must also provide "plural-forms" header.
+    Please see 'info gettext' for more details.
+
+  o Support for reading straight files, or strings (!!!)
+    Since I can imagine many different backends for reading in the MO
+    file data, I used imaginary abstract class StreamReader to do all
+    the input (check streams.php). For your convenience, I've already
+    provided two classes for reading files: FileReader and
+    StringReader (CachedFileReader is a combination of the two: it
+    loads entire file contents into a string, and then works on that).
+    See example below for usage. You can for instance use StringReader
+    when you read in data from a database, or you can create your own
+    derivative of StreamReader for anything you like.
+
+
+Bugs
+
+    Report them on https://bugs.launchpad.net/php-gettext
+
+Usage
+
+    Put files streams.php and gettext.php somewhere you can load them
+    from, and require 'em in where you want to use them.
+
+    Then, create one 'stream reader' (a class that provides functions
+    like read(), seekto(), currentpos() and length()) which will
+    provide data for the 'gettext_reader', with eg.
+      $streamer = new FileStream('data.mo');
+
+    Then, use that as a parameter to gettext_reader constructor:
+      $wohoo = new gettext_reader($streamer);
+
+    If you want to disable pre-loading of entire message catalog in
+    memory (if, for example, you have a multi-thousand message catalog
+    which you'll use only occasionally), use "false" for second
+    parameter to gettext_reader constructor:
+      $wohoo = new gettext_reader($streamer, false);
+
+    From now on, you have all the benefits of gettext data at your
+    disposal, so may run:
+      print $wohoo->translate("This is a test");
+      print $wohoo->ngettext("%d bird", "%d birds", $birds);
+
+    You might need to pass parameter "-k" to xgettext to make it
+    extract all the strings. In above example, try with
+      xgettext -ktranslate -kngettext:1,2 file.php
+    what should create messages.po which contains two messages for
+    translation.
+
+    I suggest creating simple aliases for these functions (see
+    example/pigs.php for how do I do it, which means it's probably a
+    bad way).
+
+
+Usage with gettext.inc (standard gettext interfaces emulation)
+
+    Check example in examples/pig_dropin.php, basically you include
+    gettext.inc and use all the standard gettext interfaces as
+    documented on:
+
+       http://www.php.net/gettext
+
+    The only catch is that you can check return value of setlocale()
+    to see if your locale is system supported or not.
+
+
+Example
+
+    See in examples/ subdirectory. There are a couple of files.
+    pigs.php is an example, serbian.po is a translation to Serbian
+    language, and serbian.mo is generated with
+       msgfmt -o serbian.mo serbian.po
+    There is also simple "update" script that can be used to generate
+    POT file and to update the translation using msgmerge.
+
+TODO:
+
+  o Improve speed to be even more comparable to the native gettext
+    implementation.
+
+  o Try to use hash tables in MO files: with pre-loading, would it
+    be useful at all?
+
+Never-asked-questions:
+
+  o Why did you mark this as version 1.0 when this is the first code
+    release?
+
+    Well, it's quite simple. I consider that the first released thing
+    should be labeled "version 1" (first, right?). Zero is there to
+    indicate that there's zero improvement and/or change compared to
+    "version 1".
+
+    I plan to use version numbers 1.0.* for small bugfixes, and to
+    release 1.1 as "first stable release of version 1".
+
+    This may trick someone that this is actually useful software, but
+    as with any other free software, I take NO RESPONSIBILITY for
+    creating such a masterpiece that will smoke crack, trash your
+    hard disk, and make lasers in your CD device dance to the tune of
+    Mozart's 40th Symphony (there is one like that, right?).
+
+  o Can I...?
+
+    Yes, you can. This is free software (as in freedom, free speech),
+    and you might do whatever you wish with it, provided you do not
+    limit freedom of others (GPL).
+
+    I'm considering licensing this under LGPL, but I *do* want
+    *every* PHP-gettext user to contribute and respect ideas of free
+    software, so don't count on it happening anytime soon.
+
+    I'm sorry that I'm taking away your freedom of taking others'
+    freedom away, but I believe that's neglible as compared to what
+    freedoms you could take away. ;-)
+
+    Uhm, whatever.

+		  GNU LESSER GENERAL PUBLIC LICENSE

+		       Version 2.1, February 1999

+

+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.

+     59 Temple Place, Suite 330, Boston, MA  02111-1307  USA

+ Everyone is permitted to copy and distribute verbatim copies

+ of this license document, but changing it is not allowed.

+

+[This is the first released version of the Lesser GPL.  It also counts

+ as the successor of the GNU Library Public License, version 2, hence

+ the version number 2.1.]

+

+			    Preamble

+

+  The licenses for most software are designed to take away your

+freedom to share and change it.  By contrast, the GNU General Public

+Licenses are intended to guarantee your freedom to share and change

+free software--to make sure the software is free for all its users.

+

+  This license, the Lesser General Public License, applies to some

+specially designated software packages--typically libraries--of the

+Free Software Foundation and other authors who decide to use it.  You

+can use it too, but we suggest you first think carefully about whether

+this license or the ordinary General Public License is the better

+strategy to use in any particular case, based on the explanations below.

+

+  When we speak of free software, we are referring to freedom of use,

+not price.  Our General Public Licenses are designed to make sure that

+you have the freedom to distribute copies of free software (and charge

+for this service if you wish); that you receive source code or can get

+it if you want it; that you can change the software and use pieces of

+it in new free programs; and that you are informed that you can do

+these things.

+

+  To protect your rights, we need to make restrictions that forbid

+distributors to deny you these rights or to ask you to surrender these

+rights.  These restrictions translate to certain responsibilities for

+you if you distribute copies of the library or if you modify it.

+

+  For example, if you distribute copies of the library, whether gratis

+or for a fee, you must give the recipients all the rights that we gave

+you.  You must make sure that they, too, receive or can get the source

+code.  If you link other code with the library, you must provide

+complete object files to the recipients, so that they can relink them

+with the library after making changes to the library and recompiling

+it.  And you must show them these terms so they know their rights.

+

+  We protect your rights with a two-step method: (1) we copyright the

+library, and (2) we offer you this license, which gives you legal

+permission to copy, distribute and/or modify the library.

+

+  To protect each distributor, we want to make it very clear that

+there is no warranty for the free library.  Also, if the library is

+modified by someone else and passed on, the recipients should know

+that what they have is not the original version, so that the original

+author's reputation will not be affected by problems that might be

+introduced by others.

+

+  Finally, software patents pose a constant threat to the existence of

+any free program.  We wish to make sure that a company cannot

+effectively restrict the users of a free program by obtaining a

+restrictive license from a patent holder.  Therefore, we insist that

+any patent license obtained for a version of the library must be

+consistent with the full freedom of use specified in this license.

+

+  Most GNU software, including some libraries, is covered by the

+ordinary GNU General Public License.  This license, the GNU Lesser

+General Public License, applies to certain designated libraries, and

+is quite different from the ordinary General Public License.  We use

+this license for certain libraries in order to permit linking those

+libraries into non-free programs.

+

+  When a program is linked with a library, whether statically or using

+a shared library, the combination of the two is legally speaking a

+combined work, a derivative of the original library.  The ordinary

+General Public License therefore permits such linking only if the

+entire combination fits its criteria of freedom.  The Lesser General

+Public License permits more lax criteria for linking other code with

+the library.

+

+  We call this license the "Lesser" General Public License because it

+does Less to protect the user's freedom than the ordinary General

+Public License.  It also provides other free software developers Less

+of an advantage over competing non-free programs.  These disadvantages

+are the reason we use the ordinary General Public License for many

+libraries.  However, the Lesser license provides advantages in certain

+special circumstances.

+

+  For example, on rare occasions, there may be a special need to

+encourage the widest possible use of a certain library, so that it becomes

+a de-facto standard.  To achieve this, non-free programs must be

+allowed to use the library.  A more frequent case is that a free

+library does the same job as widely used non-free libraries.  In this

+case, there is little to gain by limiting the free library to free

+software only, so we use the Lesser General Public License.

+

+  In other cases, permission to use a particular library in non-free

+programs enables a greater number of people to use a large body of

+free software.  For example, permission to use the GNU C Library in

+non-free programs enables many more people to use the whole GNU

+operating system, as well as its variant, the GNU/Linux operating

+system.

+

+  Although the Lesser General Public License is Less protective of the

+users' freedom, it does ensure that the user of a program that is

+linked with the Library has the freedom and the wherewithal to run

+that program using a modified version of the Library.

+

+  The precise terms and conditions for copying, distribution and

+modification follow.  Pay close attention to the difference between a

+"work based on the library" and a "work that uses the library".  The

+former contains code derived from the library, whereas the latter must

+be combined with the library in order to run.

+

+		  GNU LESSER GENERAL PUBLIC LICENSE

+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION

+

+  0. This License Agreement applies to any software library or other

+program which contains a notice placed by the copyright holder or

+other authorized party saying it may be distributed under the terms of

+this Lesser General Public License (also called "this License").

+Each licensee is addressed as "you".

+

+  A "library" means a collection of software functions and/or data

+prepared so as to be conveniently linked with application programs

+(which use some of those functions and data) to form executables.

+

+  The "Library", below, refers to any such software library or work

+which has been distributed under these terms.  A "work based on the

+Library" means either the Library or any derivative work under

+copyright law: that is to say, a work containing the Library or a

+portion of it, either verbatim or with modifications and/or translated

+straightforwardly into another language.  (Hereinafter, translation is

+included without limitation in the term "modification".)

+

+  "Source code" for a work means the preferred form of the work for

+making modifications to it.  For a library, complete source code means

+all the source code for all modules it contains, plus any associated

+interface definition files, plus the scripts used to control compilation

+and installation of the library.

+

+  Activities other than copying, distribution and modification are not

+covered by this License; they are outside its scope.  The act of

+running a program using the Library is not restricted, and output from

+such a program is covered only if its contents constitute a work based

+on the Library (independent of the use of the Library in a tool for

+writing it).  Whether that is true depends on what the Library does

+and what the program that uses the Library does.

+  

+  1. You may copy and distribute verbatim copies of the Library's

+complete source code as you receive it, in any medium, provided that

+you conspicuously and appropriately publish on each copy an

+appropriate copyright notice and disclaimer of warranty; keep intact

+all the notices that refer to this License and to the absence of any

+warranty; and distribute a copy of this License along with the

+Library.

+

+  You may charge a fee for the physical act of transferring a copy,

+and you may at your option offer warranty protection in exchange for a

+fee.

+

+  2. You may modify your copy or copies of the Library or any portion

+of it, thus forming a work based on the Library, and copy and

+distribute such modifications or work under the terms of Section 1

+above, provided that you also meet all of these conditions:

+

+    a) The modified work must itself be a software library.

+

+    b) You must cause the files modified to carry prominent notices

+    stating that you changed the files and the date of any change.

+

+    c) You must cause the whole of the work to be licensed at no

+    charge to all third parties under the terms of this License.

+

+    d) If a facility in the modified Library refers to a function or a

+    table of data to be supplied by an application program that uses

+    the facility, other than as an argument passed when the facility

+    is invoked, then you must make a good faith effort to ensure that,

+    in the event an application does not supply such function or

+    table, the facility still operates, and performs whatever part of

+    its purpose remains meaningful.

+

+    (For example, a function in a library to compute square roots has

+    a purpose that is entirely well-defined independent of the

+    application.  Therefore, Subsection 2d requires that any

+    application-supplied function or table used by this function must

+    be optional: if the application does not supply it, the square

+    root function must still compute square roots.)

+

+These requirements apply to the modified work as a whole.  If

+identifiable sections of that work are not derived from the Library,

+and can be reasonably considered independent and separate works in

+themselves, then this License, and its terms, do not apply to those

+sections when you distribute them as separate works.  But when you

+distribute the same sections as part of a whole which is a work based

+on the Library, the distribution of the whole must be on the terms of

+this License, whose permissions for other licensees extend to the

+entire whole, and thus to each and every part regardless of who wrote

+it.

+

+Thus, it is not the intent of this section to claim rights or contest

+your rights to work written entirely by you; rather, the intent is to

+exercise the right to control the distribution of derivative or

+collective works based on the Library.

+

+In addition, mere aggregation of another work not based on the Library

+with the Library (or with a work based on the Library) on a volume of

+a storage or distribution medium does not bring the other work under

+the scope of this License.

+

+  3. You may opt to apply the terms of the ordinary GNU General Public

+License instead of this License to a given copy of the Library.  To do

+this, you must alter all the notices that refer to this License, so

+that they refer to the ordinary GNU General Public License, version 2,

+instead of to this License.  (If a newer version than version 2 of the

+ordinary GNU General Public License has appeared, then you can specify

+that version instead if you wish.)  Do not make any other change in

+these notices.

+

+  Once this change is made in a given copy, it is irreversible for

+that copy, so the ordinary GNU General Public License applies to all

+subsequent copies and derivative works made from that copy.

+

+  This option is useful when you wish to copy part of the code of

+the Library into a program that is not a library.

+

+  4. You may copy and distribute the Library (or a portion or

+derivative of it, under Section 2) in object code or executable form

+under the terms of Sections 1 and 2 above provided that you accompany

+it with the complete corresponding machine-readable source code, which

+must be distributed under the terms of Sections 1 and 2 above on a

+medium customarily used for software interchange.

+

+  If distribution of object code is made by offering access to copy

+from a designated place, then offering equivalent access to copy the

+source code from the same place satisfies the requirement to

+distribute the source code, even though third parties are not

+compelled to copy the source along with the object code.

+

+  5. A program that contains no derivative of any portion of the

+Library, but is designed to work with the Library by being compiled or

+linked with it, is called a "work that uses the Library".  Such a

+work, in isolation, is not a derivative work of the Library, and

+therefore falls outside the scope of this License.

+

+  However, linking a "work that uses the Library" with the Library

+creates an executable that is a derivative of the Library (because it

+contains portions of the Library), rather than a "work that uses the

+library".  The executable is therefore covered by this License.

+Section 6 states terms for distribution of such executables.

+

+  When a "work that uses the Library" uses material from a header file

+that is part of the Library, the object code for the work may be a

+derivative work of the Library even though the source code is not.

+Whether this is true is especially significant if the work can be

+linked without the Library, or if the work is itself a library.  The

+threshold for this to be true is not precisely defined by law.

+

+  If such an object file uses only numerical parameters, data

+structure layouts and accessors, and small macros and small inline

+functions (ten lines or less in length), then the use of the object

+file is unrestricted, regardless of whether it is legally a derivative

+work.  (Executables containing this object code plus portions of the

+Library will still fall under Section 6.)

+

+  Otherwise, if the work is a derivative of the Library, you may

+distribute the object code for the work under the terms of Section 6.

+Any executables containing that work also fall under Section 6,

+whether or not they are linked directly with the Library itself.

+

+  6. As an exception to the Sections above, you may also combine or

+link a "work that uses the Library" with the Library to produce a

+work containing portions of the Library, and distribute that work

+under terms of your choice, provided that the terms permit

+modification of the work for the customer's own use and reverse

+engineering for debugging such modifications.

+

+  You must give prominent notice with each copy of the work that the

+Library is used in it and that the Library and its use are covered by

+this License.  You must supply a copy of this License.  If the work

+during execution displays copyright notices, you must include the

+copyright notice for the Library among them, as well as a reference

+directing the user to the copy of this License.  Also, you must do one

+of these things:

+

+    a) Accompany the work with the complete corresponding

+    machine-readable source code for the Library including whatever

+    changes were used in the work (which must be distributed under

+    Sections 1 and 2 above); and, if the work is an executable linked

+    with the Library, with the complete machine-readable "work that

+    uses the Library", as object code and/or source code, so that the

+    user can modify the Library and then relink to produce a modified

+    executable containing the modified Library.  (It is understood

+    that the user who changes the contents of definitions files in the

+    Library will not necessarily be able to recompile the application

+    to use the modified definitions.)

+

+    b) Use a suitable shared library mechanism for linking with the

+    Library.  A suitable mechanism is one that (1) uses at run time a

+    copy of the library already present on the user's computer system,

+    rather than copying library functions into the executable, and (2)

+    will operate properly with a modified version of the library, if

+    the user installs one, as long as the modified version is

+    interface-compatible with the version that the work was made with.

+

+    c) Accompany the work with a written offer, valid for at

+    least three years, to give the same user the materials

+    specified in Subsection 6a, above, for a charge no more

+    than the cost of performing this distribution.

+

+    d) If distribution of the work is made by offering access to copy

+    from a designated place, offer equivalent access to copy the above

+    specified materials from the same place.

+

+    e) Verify that the user has already received a copy of these

+    materials or that you have already sent this user a copy.

+

+  For an executable, the required form of the "work that uses the

+Library" must include any data and utility programs needed for

+reproducing the executable from it.  However, as a special exception,

+the materials to be distributed need not include anything that is

+normally distributed (in either source or binary form) with the major

+components (compiler, kernel, and so on) of the operating system on

+which the executable runs, unless that component itself accompanies

+the executable.

+

+  It may happen that this requirement contradicts the license

+restrictions of other proprietary libraries that do not normally

+accompany the operating system.  Such a contradiction means you cannot

+use both them and the Library together in an executable that you

+distribute.

+

+  7. You may place library facilities that are a work based on the

+Library side-by-side in a single library together with other library

+facilities not covered by this License, and distribute such a combined

+library, provided that the separate distribution of the work based on

+the Library and of the other library facilities is otherwise

+permitted, and provided that you do these two things:

+

+    a) Accompany the combined library with a copy of the same work

+    based on the Library, uncombined with any other library

+    facilities.  This must be distributed under the terms of the

+    Sections above.

+

+    b) Give prominent notice with the combined library of the fact

+    that part of it is a work based on the Library, and explaining

+    where to find the accompanying uncombined form of the same work.

+

+  8. You may not copy, modify, sublicense, link with, or distribute

+the Library except as expressly provided under this License.  Any

+attempt otherwise to copy, modify, sublicense, link with, or

+distribute the Library is void, and will automatically terminate your

+rights under this License.  However, parties who have received copies,

+or rights, from you under this License will not have their licenses

+terminated so long as such parties remain in full compliance.

+

+  9. You are not required to accept this License, since you have not

+signed it.  However, nothing else grants you permission to modify or

+distribute the Library or its derivative works.  These actions are

+prohibited by law if you do not accept this License.  Therefore, by

+modifying or distributing the Library (or any work based on the

+Library), you indicate your acceptance of this License to do so, and

+all its terms and conditions for copying, distributing or modifying

+the Library or works based on it.

+

+  10. Each time you redistribute the Library (or any work based on the

+Library), the recipient automatically receives a license from the

+original licensor to copy, distribute, link with or modify the Library

+subject to these terms and conditions.  You may not impose any further

+restrictions on the recipients' exercise of the rights granted herein.

+You are not responsible for enforcing compliance by third parties with

+this License.

+

+  11. If, as a consequence of a court judgment or allegation of patent

+infringement or for any other reason (not limited to patent issues),

+conditions are imposed on you (whether by court order, agreement or

+otherwise) that contradict the conditions of this License, they do not

+excuse you from the conditions of this License.  If you cannot

+distribute so as to satisfy simultaneously your obligations under this

+License and any other pertinent obligations, then as a consequence you

+may not distribute the Library at all.  For example, if a patent

+license would not permit royalty-free redistribution of the Library by

+all those who receive copies directly or indirectly through you, then

+the only way you could satisfy both it and this License would be to

+refrain entirely from distribution of the Library.

+

+If any portion of this section is held invalid or unenforceable under any

+particular circumstance, the balance of the section is intended to apply,

+and the section as a whole is intended to apply in other circumstances.

+

+It is not the purpose of this section to induce you to infringe any

+patents or other property right claims or to contest validity of any

+such claims; this section has the sole purpose of protecting the

+integrity of the free software distribution system which is

+implemented by public license practices.  Many people have made

+generous contributions to the wide range of software distributed

+through that system in reliance on consistent application of that

+system; it is up to the author/donor to decide if he or she is willing

+to distribute software through any other system and a licensee cannot

+impose that choice.

+

+This section is intended to make thoroughly clear what is believed to

+be a consequence of the rest of this License.

+

+  12. If the distribution and/or use of the Library is restricted in

+certain countries either by patents or by copyrighted interfaces, the

+original copyright holder who places the Library under this License may add

+an explicit geographical distribution limitation excluding those countries,

+so that distribution is permitted only in or among countries not thus

+excluded.  In such case, this License incorporates the limitation as if

+written in the body of this License.

+

+  13. The Free Software Foundation may publish revised and/or new

+versions of the Lesser General Public License from time to time.

+Such new versions will be similar in spirit to the present version,

+but may differ in detail to address new problems or concerns.

+

+Each version is given a distinguishing version number.  If the Library

+specifies a version number of this License which applies to it and

+"any later version", you have the option of following the terms and

+conditions either of that version or of any later version published by

+the Free Software Foundation.  If the Library does not specify a

+license version number, you may choose any version ever published by

+the Free Software Foundation.

+

+  14. If you wish to incorporate parts of the Library into other free

+programs whose distribution conditions are incompatible with these,

+write to the author to ask for permission.  For software which is

+copyrighted by the Free Software Foundation, write to the Free

+Software Foundation; we sometimes make exceptions for this.  Our

+decision will be guided by the two goals of preserving the free status

+of all derivatives of our free software and of promoting the sharing

+and reuse of software generally.

+

+			    NO WARRANTY

+

+  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO

+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.

+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR

+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY

+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE

+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR

+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE

+LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME

+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.

+

+  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN

+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY

+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU

+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR

+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE

+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING

+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A

+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF

+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH

+DAMAGES.

+

+		     END OF TERMS AND CONDITIONS

+| smarty-gettext - Gettext support for Smarty    |

+|                                                |

+| Author: Sagi Bashari <sagi@boom.org.il>        |

+| URL:    http://smarty-gettext.sourceforge.net/ |

+ ------------------------------------------------

+

+smarty-gettext provides gettext support for Smarty, 

+the popular PHP templating engine (http://smarty.php.net/).

+

+This README assumes that you already know what is gettext and how to

+use it with PHP.

+

+If you don't, please visit the following websites before trying to

+use this package:

+  - http://www.php.net/gettext

+  - http://www.onlamp.com/pub/a/php/2002/06/13/php.html

+

+If you encounter problems when using the native gettext extension,

+you may want to try the php-gettext module, which emulates the behavior

+of the C extension, but is written in pure PHP:

+http://savannah.nongnu.org/projects/php-gettext/

+

+This package has two parts:

+  1. block.t.php   - The Smarty plugin.

+  2. tsmarty2c.php - A command line utility that rips gettext strings

+                     from smarty source files and converts them to C format.

+

+ ---------------------------------

+| block.t.php - The Smarty plugin |

+ ---------------------------------

+

+Installation

+------------

+

+Simply copy block.t.php to your smarty plugins directory.

+

+Usage

+------

+

+The content of the block function is the string that you want to translate.

+For example, for translating 'Hello World', use: {t}Hello World{/t}.

+

+If you have dynamic parameters that should be set inside the string, 

+pass them to the block function, and they will be replaced with %n, 

+where n is 1 for the 1st parameter and so on. 

+

+For example, {t name="sagi"}my name is %1{/t} will replace %1 with sagi.

+

+The parameter name is ignored, unless it is one of the reserved 

+names (see below). Only the parameters order matters.

+

+Example for using multiple parameters:

+{t 1='one' 2='two' 3='three'}The 1st parameter is %1, the 2nd is %2

+and the 3nd %3.{/t}

+

+NOTE: I decided to use numeric arguments instead of sprintf(), 

+mainly because its syntax is simpler for the translators 

+(especially when wanting to change the parameter order).  

+

+You can also use this method in your PHP code, by using the 

+smarty_gettext_strarg() function. It is only loaded after block.t.php is 

+included, so you probably want to copy it elsewhere. 

+I usually name the global version of this function strarg(), and use it like this:

+echo strarg(_('hi %1'), $name [,..]);

+

+By default, all the translated strings will be automatically HTML escaped.

+You may control this by setting the 'escape' parameter. Possible values:

+  - 'html' for HTML escaping, this is the default.

+  - 'js' for javascript escaping.

+  - 'url' for url escaping.

+  - 'no'/'off'/0 - disables escaping.

+Example: 

+{t escape=no url="http://www.php.net/" name="PHP website"}

+<a href="%1">%2</a>

+{/t}

+

+Plural support

+--------------

+

+The package also provides support for plural forms (see ngettext). 

+

+To provide a plural form:

+  1. Set a parameter named 'plural' with the plural version of the string.

+  2. Set a parameter named 'count' with the variable count.

+

+Plural and count are special parameters, and therefore, are not available

+as numeric arguments. If you wish to use the count value inside the string,

+you will have to set it again, as a numeric argument.

+

+Example:

+{t count=$files|@count 1=$files|@count plural="%1 files"}One file{/t}

+

+Modifier support

+----------------

+

+A Smarty modifier support is not provided by this package.

+

+I believe variables should be trnalsated in the application level

+and provided after translation to the template.

+

+If you need it anyway, it is easy to create such modifier, by simply 

+registering the PHP gettext command as one.

+

+ ------------------------------------------

+| tsmarty2c.php - the command line utility |

+ ------------------------------------------

+

+This utility will rip the translation strings from the smarty files,

+and convert them to gettext calls in C.

+

+The C output may later be used with the standard gettext tools (see xgettext).

+

+Usage:

+./tsmarty2c.php <filename or directory> <file2> <..> > smarty.c

+

+If a parameter is a directory, the template files within will

+be parsed, recursively.

+

+TIP:

+The output also contains comments that point to the location of the file 

+that the string has been ripped from. 

+

+You can use the '--add-comments' parameter of xgettext to make it include

+these comments inside the PO file (suggested by Mike van Lammeren).

+

+NOTE: 

+You may need to adjust the PHP bin path at the top of the file,

+or use 'php tsmarty2c.php' to run the script.
